Sounds really weird to me. And there are whole lists of pronouns for every conceivable gender or sexual variation making the rounds. No idea if they're parody, fringe activism, or if we're meant to take them seriously.
I've never encountered anyone that wanted me to use any of those alternative pronouns, so I think being worried about those might be just a bugbear for people who like to complain about 'crazy stupid leftists' more than anything else.
Personally, I'd just avoid pronouns around people like that, or if they're the kind of annoying I expect, avoid them altogether.
